Geotechnical study in Becerreá

In Becerreá, the subsoil is dominated by slates and schists, which represent the majority of the geological materials in the area. These soils are generally hard and have low permeability, and they usually provide a good bearing capacity for shallow and deep foundations. However, the occasional presence of shallow aquifers associated with fracturing must be taken into account when developing foundation projects.

Seismic activity in the municipality is significant, with 187 events over the last 30 years and a maximum magnitude of 4.3, indicating a high level of seismicity to be considered in structural design. In addition, the possible presence of karstification in the subsoil means that the existence of voids or dissolution processes must be checked before proceeding with the foundations. The non-clayey substratum rules out expansivity-related risks, so the main geotechnical precautions will be associated with seismicity and the potential presence of karst.
